I found this unreferenced flowers model in leaked SADX X360 symbols. It uses the Dreamcast version’s CHAO.PVM and is located in the same region as objects used in the Chao Race on DC, such as the watering can or the trumpet. What is it? Some kind of unused Chao Race object or toy? No idea.
If you want to have a look at this model, you can find it in AL_MAIN.BIN (SA1 v1.005) at 14E10C.
